#include <crypto/nrf_oberon/include/ocrypto_rsa.h>

1024-bit RSA PKCS1 V1.5 SHA-256 signature verify.

The signature s of the input message m is verified.

Parameters

s	The 128-byte signature.
m	The signed message.
m_len	Length of m.
pk	A valid 1024-bit RSA public key.

Return values

0	If the signature is valid.
-1	If verification failed.

Remarks

The key pk should be initialized with ocrypto_rsa1024_init_pub_key.
